For example, uncompressed songs in CD format have a data rate of 16 bits/channel x 2 channels x 44.1 kHz ≅ 1.4 Mbit/s, whereas AAC files on an iPod are typically compressed to 128 kbit/s, yielding a compression ratio of 10.9, for a data-rate saving of 0.91, or 91%.
The square root effectively converts the power ratio back to a voltage ratio, so the number of levels is approximately proportional to the ratio of signal RMS amplitude to noise standard deviation. This similarity in form between Shannon's capacity and Hartley's law should not be interpreted to mean that M {\displaystyle M} pulse levels can be ...
The standard logistic function is the logistic function with parameters =, =, =, which yields = + = + = / / + /.In practice, due to the nature of the exponential function, it is often sufficient to compute the standard logistic function for over a small range of real numbers, such as a range contained in [−6, +6], as it quickly converges very close to its saturation values of 0 and 1.
The carrying capacity of an environment is the maximum population size of a biological species that can be sustained by that specific environment, given the food, ...
The C/N ratio is measured in a manner similar to the way the signal-to-noise ratio (S/N) is measured, and both specifications give an indication of the quality of a communications channel. In the famous Shannon–Hartley theorem, the C/N ratio is equivalent to the S/N ratio.
The channel capacity is defined as ... there is an encoding and decoding scheme transmitting data at rate R ... For example, a signal-to-noise ratio of 30 dB ...
According to Bloomberg data, of the more than 60 analysts covering Apple on Wall Street, only four have sell or sell-equivalent ratings. Shares of Apple traded down about 1% to $242.43 in Tuesday ...
